Yes, I've been following this... some interesting discussion. Most of KV's book picks are right on, although DANCE OF THE INFIDELS is chock-full of errors or downright falsehoods, almost better read as a jazz "novel." He's sure right that Jost's FREE JAZZ remains, several decades later, one of the best books on the topic, though I'm surprised that he left John Litweiler out of the mix.
I'm enjoying KV's talk re: critics and such, and hoping to hear more about his approach to improv in the various settings/contexts that he enters or creates for himself.
